This product uses a combination of a small DC brushless motor and a planetary gear reduction box (BLDC42 G). Based on customer needs, Honltie adjusts the voltage and speed, and selects a reduction box with a higher gear ratio, achieving high torque at low voltage to meet the rotational requirements. Also, the brushless motor's temperature rise is fairly controllable, so it can easily handle nearly continuous operation. It's suitable for applications like autonomous unmanned boats, fishing kayaks, and small yachts.
